Hi
The problem is with my field meta data mapping. I have applied your points 4
and 6 and could figure out actual mapping problem and fix it.
Thank You for your pointers,they were helpful in solving my problem.
But i amnt sure why these mapping errors werent pointed when i was running
with logging enabled as
<property name="openjpa.Log" value="DefaultLevel=TRACE, Runtime=TRACE,
Tool=TRACE/>
